Title: Burglarproof device for vehicle
Inventor: YUKITOMO KAZUO
IPC: B60R25/10
Filed: 1987-04-03
Abstract: PURPOSE:To aim at prevention of having a vehicle stolen while loading or unloading a cargo on or off the vehicle after getting off the vehicle by keeping a burglarproof device in a functioning condition when locking side doors, back doors, etc., and, at the same time, by not releasing the burglarproof device but keeping it in a continuation condition when the back door lock is in an unlocked condition. CONSTITUTION:Key detecting means 16 and 17 to lock a side door 3 and a back door 4, respectively, are to be provided as well as open-close detecting means 13-15 on the side door 3, the back door 4 and on a hood 5, respectively. The burglarproof device is to be in a functioning condition by detecting that each open-close means 13-15, an ignition switch and a key switch are all closed. When the lock of the back door 4 is unlocked with a key under this condition, the burglarproof device is not to be released but to keep the function in a continuation condition. Safety can be secured in this manner as the burglarproof device is continuously in a functioning condition even when the back door lock is unlocked with a key to load or unload a cargo after getting off the vehicle.

IPC: B41J7/02
Filed: 1979-07-02
Abstract: PURPOSE: To accomplish reliable paper feeding with a stable timing by arranging the detection drum for generating the timing pulse and the eccentric cam on the common shaft in the paper feeder of the line printer provided with the clutch mechanism.  
     CONSTITUTION: The eccentric cam 2 and the detection drum 3 having the detection magnet 4 fixed thereon are mounted on the common shaft in such a manner as to be rotatable together, and one timing pulse is generated each time the shaft 1 turns by one cycle with the detection coil 6. It is so arranged that the timing pulse is generated when the eccentric cam 2 reaches roughly the lowest position so that the cam 2 reaches the lowest position at the moment when the energization of the magnet 14 starts. At the start of the energization, the arm 9 and the armature 12 are engaged but as the cam 2 reaches the highest position, the arm 9 is disengaged from the armature to push the clutch lever whereby the paper is fed. With further turning of the cam 2, the arm 9 engages with the armature again. Thus, it is checked from turning until the magnet is energized to push the lever 15.

Title: Heat exchanger
Inventor: OGAWA KAZUO
IPC: F28D1/053
Filed: 1987-04-07
Abstract: PURPOSE:To reduce the difference of thermal expansion between a header end plate and a reinforcing member and prevent the deformation of the header end plate by a method wherein a thermal insulation layer is arranged on an inner surface of the header end plate. CONSTITUTION:A primary fluid inlet header 22 and a primary fluid outlet header 44 are connected with a tube 33 for performing heat exchanging operation. End plate surfaces of the primary fluid inlet header 11 and the primary fluid outlet header 44 are provided with reinforcing members 66 for preventing vibration and corrosion, and a thermal insulation layer 77 is arranged on the inner surfaces of both headers. This thermal insulation layer is made of material having a lower thermal conductivity than that of the header material for example, ceramics. With such an arrangement as above, since the heat of the primary fluid is hard to be transmitted to the header end plates and the reinforcing member to be connected to the header end plates, an increase in temperature of the header end plates and the reinforcing members is restricted. The relative difference in temperature between the header end plate and the reinforcing members is reduced and a difference in thermal expansion of both members is also decreased, so that a deformation of the header end plates caused by a thermal stress is restricted.
